GAS-STOVE.

SPECIFICATION forming part of Letters Patent No. 316,027, dated April 21, 1885. Application filed March 6, 1884. (No model.) Patented in England January 5, 184, No. 80!).

To all whom it may concern:

Be it known that I, THOMAS FLETCHER, a subject of the Queen of Great Britain,residing at \Varrington, in the county of Lancaster and Kingdom of Great Britain,have invented certain new and useful Improvements in Gas- Stoves; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

This invention relates to certain improve ments in gas-stoves, all of which will be fully and clearly shown and described by reference to the accompanying drawings, in which- Figure 1 is a sectional elevation'of the apparatus, showing a section through the outer casing, and also through the dash-plate, shallow circular watertray,an annular water space or vessel, and a side elevation of a portion of the water-jet tube and nozzle. Fig. 2 represents a plan or top view of the casing dashplate and a portion of the water-jet tube, the burner not being shown.

These improvements relate to the construction of an apparatus for heating water by bringing it into actual contact with the heated products of the combustion of gas; and they consistin the combination of a water jet or jets, a shallow circular tray, and an annular water-space contained within a suitable casing, in the bottom of which an opening is formed for the admission of the heated products of combustion from the gas-burner placed below the apparatus. With the water jet or jets, circular tray, and easing there may also be combined a dash plate, as hereinafter described.

In carrying out these improvements I construct a casing of cylindrical or other convenient form, a, of metal or other suitable material.

When the use of a dash-plate a is advisable-as, for example, when a jet-tube with a single central orifice is employedI suspend or attach it immediately below the top of the passage into the apparatus of the products of combustion. The opening must be of smaller diameter than the tray above it, so that no water may fall through the opening and upon the burner I) when the apparatus is at work. The annular waterspace is provided with an outlet for the delivery of the heated Water collected therein, the water being conducted by a spout, W, or other well-known means.

. The action of the apparatus may be described asfollows: The gas in the burner below the apparatus being lighted and the water turned on,the jets of water,striking each other or the dash-plates,are diffused throughout the interior of the casing as spray, which, falling slowly, is collected partly in the annular space and partly in the tray, from which it overflows into the annular space, from which it passes off through the outlet b".

The only portions of the apparatus exposed to the possible action of the flame or heated gases, being covered in the inner side with water, are always maintained at a lower tem perature than that of boiling water, and are thus protected from corrosion, local action, or injury from the heat.

I claim as my invention In an apparatus for heating water by means of gas, a casing, a, dash-plate, a, shallow tray a, an annular water-vessel a surrounding the opening I), and ajet-tube, (L in combination with a suitable gas-burner, substantially as and for the purposes described. 7

In testimony whereof I affix my signature in presence of two witnesses. 1
